The United States Constitution is the "supreme law of the land" and no laws, state or federal, may violate it.
Each state has its own constitution. South Carolina laws may not conflict with the South Carolina Constitution or the United States Constitution.
An online version of the Constitution of the United States of America, annotated with analysis and interpretation by the U.S. Supreme Court, is available on the Congress.gov website. This online "Constitution Annotated" is free, easy to navigate, and updated regularly by the Library of Congress.
You can also view the Constitution of the United States and read about its creation and ratification on the website for the National Archives.
There are two print annotated versions of the United States Code — U.S.C.A., published by West Publishing and U.S.C.S., published by LexisNexis. Both include volumes of the text of the United States Constitution annotated with cases interpreting its provisions. Both are also available through subscriptions to Westlaw (U.S.C.A.) and LexisNexis (U.S.C.S.), respectively.
The print South Carolina Code Annotated includes a Constitution volume that contains the text of both the South Carolina Constitution and the United States Constitution. Both constitutions are annotated with summaries and citations for South Carolina cases that have interpreted individual constitutional provisions.
Both constitutions are indexed in the general A-I and J-Z subject indexes for the South Carolina Code Annotated. There is also an index at the end of the Constitution volume.
